Not all Delorme units: The "tripmate" was easy to get going, which was the earlier bright yellow Delorme unit. It wanted a string, "ASTRAL" I think, to be sent to it, which it put out periodically on it's TX line. The easiest way was to wire pins 2 to 3 and it would talk to itself, receive the string it was looking for, and start putting out NMEA sentences. Some people put in a momentary switch for that, others wired them together permanently then only wired one wire and ground to the laptop or tracker from there. Unfortunately you've got the later model which I think put out Rockwell protocol sentences? Do a Google search for "earthmate APRS" and see if someone's solved the problem. -- Curt, WE7U. <http://www.eskimo.com/~archer> APRS: Where it's at! <http://www.xastir.org> Lotto: A tax on people who are bad at math. - unknown Windows: Microsoft's tax on computer illiterates. - WE7U.
